[ARSCLIST] storage of mothers, masters, and stampers

[Hannah Frost <hfrost@xxxxxxxxxxxx>]

Hi folks,

Can anyone provide guidance on the proper storage of metal mothers,  
masters, and stampers?

We are preparing a collection of such discs for long-term storage in  
a collections storage facility (where it is 50º F +/-1º and 38% RH  
+/- 3%).  The items are 13-14 in. in diameter, and appear to be made  
of nickel, copper, and possibly zinc (or alloys of same?). I can't  
help but wonder if most of the likely standard-issue archival  
housings -- the buffered sleeves and boxes designed for transcription  
discs -- are not be perfectly suited in terms of design and materials  
for these kinds of sound recordings.

Are custom enclosures required? Do the conventional shelving  
guidelines -- vertical, not too tight, etc. -- apply? Any information  
or ideas are welcome.

Many thanks,

Hannah
